Powder Metal Advantage
- Can produce parts from materials capable of high-temperature service and extreme durability at lower cost and at reduced difficulty. Think of stainless steels that are subject to high temperatures in exhaust systems, etc.
- Can maintain high production rates for parts, even complex parts.
- Machining is mostly unnecessary due to the net shaping capabilities of powder metallurgy. Less secondary machining means lower labor costs.
- High level of control is achievable using metal powders and sintering. This allows fine tuning of electrical and magnetic properties, density, damping, toughness, and hardness.
- High-temperature sintering offers substantial improvements in tensile strength, bending fatigue strength, and impact energy.
- There are often size limitations to PM parts that can make certain designs impossible to produce. The biggest presses in the industry are about 1,500 tons. This limits practical part size to about 40-50 sq. in. of planar area. More realistically, average press sizes are in the 500 ton range, so plan accordingly for your part development.
- Complex-shaped parts can also be challenging to make. However, high-skill metal parts manufacturers can get past this challenge, and even help you with your design.
- Parts are generally not as strong or as ductile as cast irons or forged parts.
